   $cityid=$nRow1['cty_id'];
   $cty_name=$nRow1['cty_name'];

    <li><a href="show_adlist.php?cty_id="<?php .$cityid."&cty_name=".$cty_name;?>>Search    Ads in </li>

<li><a href="show_adlist.php?cty_id="+<?php echo $cityid; ?>+"&cty_name="+<?php echo $cty_name;?>+" >Search    Ads in </li>

Try adding echo. Also make sure you end the php code after cty_name.

$cityid=$nRow1['cty_id'];
$cty_name=$nRow1['cty_name'];

?>

<li><a href="show_adlist.php?cty_id="<?php echo $cityid."&cty_name=".$cty_name; ?>">Search    Ads in </li>
